What do you guys think of Gaenor, the crazy Bosmer encountered in Tribunal? Did you enjoy his eccentric dialogue and fighting him when he returned decked out in full ebony armor? Or do you think his quest was an out-of-place encounter that ended up being an annoyance?

He was made so that very high level characters still had something to challenge them. So in that way, he's a great addition.
(like the Ebony Warrior in Skyrim)

Personally, I avoid him. I'm not giving him one gold piece, just to get my butt handed to me later
But he's funny to talk to, and every time I see him I think, "GG, Bethesda.... G freaking G!" ... and then run away.
